** BETA RELEASE
09-15-03 v1.5.7 Fixed error where messages were rejected if source server was on RBL blacklist and but the email sender was on a whitelist.
08-01-03 v1.5.6 Fix SMTP parsing to handle all remaining "holes" in line buffering protocol.
                Add support for "disabled SMTP commands" to restrict access to the backend STMP server (ex: bdat, xexch50, ...)
                Added new header line "X-BCware-Sender: ..." to log original specified sender in message header
                Removed verbose logging of startup options from the registry. 
06-19-03 v1.5.3 Revamp of network buffering code - handles "holes" in line buffering protocol.
06-07-03 v1.5.2 Fix bug caused by case sensitive comparision of black/white lists and local domain lists
                Fix bug which prevented mail receive if no local domain was configured (rejected everything as a relay attempt)
05-31-03 v1.5.0 Support for relay / local domains.   If a set of local domains are defined, NoSPAM will prevent sending (relaying) unless the 
				client authenticates with the backend mail server.    Local domains are also used to filter rejection emails so they are only
				send to senders on non-local domains.  This prevents rejection emails being send to local mail users.
02-23-03 v1.4.4 Support for white and blacklist email addresses
				Fix bug which caused NoSPAM to crash on restart if no description was entered for a new RBL list
				Report DNS name of MX lookup server used for mail pass through check when logging rejected message
				All logs files are no prefixed by "nospam" rather than "maps"
				Revamped logging support for connection and sessions.  Now logs to file "nospam_diagNNNNN.log"
